Auditory brainstem evoked response as a hearing test in infants and children: a follow up study.

In recent years the auditory brainstem evoked response (BSER) has become an established aid in assessing hearing in unco-operative subjects. We have reviewed our experience with this technique in 293 infants and children aged less than 11 years. We have found that the threshold for click BSER correlates well with the average audiometric threshold in the 2-4 kHz range. We have had encouraging preliminary experience to support the claim by other workers that 500 Hz stimuli may be used to assess low tone auditory function. In interpreting results it is important to appreciate that hearing levels may fluctuate with disorders such as otitis media and occasionally in cases of meningitis. Caution is also advised in interpreting results in cases where central nervous system pathology capable of affecting auditory pathways is known to exist.
